Hi! I've been trying for a while to get openmpi (from 1.0.1 to 1.1.1b4) and blacs to work together.
Everything compiles ok but when running the blacs tests i get errors. ============ INTEGER SDRV TESTS: BEGIN. PROCESS { 0, 1} REPORTS ERRORS IN TEST# 1: Invalid element at A( 1, 1): Expected= 640084; Received= -54412 Invalid element at A( 2, 1): Expected= 683078; Received= -2 Invalid element at A( 1, 2): Expected= -54412; Received= -747635 Invalid element at A( 2, 2): Expected= -747635; Received= -2 PROCESS { 0, 1} DONE ERROR REPORT FOR TEST# 1. ============ and others like it. (For 1.0.1 up to 1.1b2 i only got errors in the INTEGER AMX and later openmpi is compiled with gcc 4.0, MX 1.1.3 on a dual opteron. blacs is compiled as per the FAQ from openmpi the tests are run all 4 tasks on the same dual node. I'm probably doing something stupid somewhere but i'm sofar unable to find where and what. Exact config params for openmpi are export OPT="-O2 -march=k8" export CC=gcc CFLAGS="$OPT" CXX=g++ CXXFLAGS="$OPT" F77=g77 export FFLAGS="$OPT" FC=gfortran FCFLAGS="$OPT -ff2c" ./configure --enable-smp-locks --with-tm=/lap/torque --with-pic --enable-cxx-exceptions --with-wrapper-fcflags=-ff2c Please assist. -- Ake Sandgren, HPC2N, Umea University, S-90187 Umea, Sweden Internet: a...@hpc2n.umu.se Phone: +46 90 7866134 Fax: +46 90 7866126 Mobile: +46 70 7716134 WWW: http://www.hpc2n.umu.se
